PEDV and other pathogens survive in feed for weeks.

PEDV and other pathogens survive in feed for weeks.In 2013-2014, infection of pig farms with porcine epidemic diarrhea virus (PEDV) was a frequent event, even on farms using the highest level of biosecurity. Investigations into the occurrence showed one common denominator across many of these farms which was feed outage in a specific subpopulation of animals, requiring an emergency feed delivery to a specific bin onsite. The pigs consuming the feed from the emergency delivery were the first to become infected. Samples from inside the suspect feed bins were collected and sent to a diagnostic lab for testing. The results showed the feed did contain live PEDV, an outcome that had not been confirmed before.
